Abstract :
Tunnel junctions have attracted a great deal of renewed interests in the field of optoelectronic devices in recent years due to their applications in edge-emitting lasers, short- and long-wavelength VCSELs. In addition to enabling low resistance conduction, tunnel junctions can easily be destroyed by ion-implantation or dopant diffusion, thus forming an effective current blocking layer. This work explores the properties of tunnel junctions formed in InxGa1-xAsyP1-y (λ g=1.3 μm) and their feasibility as current blocking layers in 1.55 μm wavelength optoelectronic devices
